A two-stage, double-acting compressor is to deliver 90 lb/min of air from 14.3 psia and 90 ̊F to a final pressure of 185 psia. The normal barometer is 29.8 in. Hg and the temperature is 80 ̊F. The pressure drop in the intercooler is 3 psi and the temperature of the air at the exit of the intercooler is 90 ̊F, the speed is 210 rpmand pV1.34 =C during compression and expansion. The clearance is 5% for both cylinder. The temperature of the cooling water increase by 18 ̊F. Find: a) The mass of cooling water to be circulated about each cylinder and through the intercooler b) The work c) If, for the low pressure cylinder, L/D = 0.68 and if both cylinders have the same stroke, what should be the cylinder dimensions?

Methanol (SG=0.792) is contained in a large tank under a pressure of 350000 Pa absolute. When a valve on the bottom of the tank is opened, the methanol drains freely though a 0.02 m ID tube whose outlet is 7.00 m below the surface of the methanol. The pressure at the outlet of the discharge pipe is 101325 Pa. Some useful constants and conversions: g = 9.8 m/s2 , Pref = 1000 kg/m3 . a. Draw the system. Label points I and 2 (where you will define A= 2-1) and label the variables with values b Write the general form of the energy balance. Cancel out negligible terms, and state the keyword/assumption to justify. Simplify to the resultant energy balance. c.) Assume the diameter of the tank is very big compared to the drain tube velocity, which make the velocity of liquid in the tank equal to zero. Estimate the methanol discharge velocity in the drain tube in m/s. *hint: divide your EB by m to eliminate m and V. Recall, n = pV = pvA and = v/m=1/p
